The most important publications on the Continent, as 

 bearing on our fauna, which have been published since Bate 

 and Westwood, and which should be consulted by a naturalist

 which have not yet been met with in our islands. 



My object in this short paper is to draw attention to the 

 Land Isopoda in the hope that naturalists may be induced to
